Title: Rare earth element silicate sintered compact and its production
Inventor: OU USOU
IPC: C04B35/16
Filed: 1994-06-24
Abstract: PURPOSE:To obtain a sintered compact excellent in oxidation resistance at high temperatures and reduced in the deterioration of mechanical strength in a temperature range from room temperature to a high temperature of 1400 deg.C by sintering a molded product comprising silicon dioxide and the oxide of the group IIIa element in the periodic table in a specified ratio at a prescribed temperature. CONSTITUTION:This sintered compact is obtained by sintering a molded product comprising silicon dioxide (SiO2) and the oxide (RE2O3) of the group IIIa element in the periodic table in a molar ratio of 1:(0.4-1.2) at 1100-1850 deg.C in an oxidizing or non-oxidizing atmosphere. The sintered compact produced by the method for producing the sintered compact does substantially not cause the deformation of the composition, because the disilicate and the monosilicate are low in the symmetric properties of their crystal structures and have mainly a monoclinic crystal structure, hardly lowers the mechanical strength even at a high temperature such as 1400 deg.C, and exhibits corrosion resistance comparable to that of an oxide ceramic such as alumina (Al2O3), zirconia (ZrO2) or magnesia (MgO).

Title: Pipe coupling
Inventor: HOSOMI MIKIYA
IPC: F16L27/06
Filed: 1994-06-24
Abstract: PURPOSE:To reduce the generation of bending vibration and the generation of noise in a car occasioned thereby by bringing outer and inner spherical cases into contact with each other in a pipe coupling combined state and into a state to be constrained by each other. CONSTITUTION:A first pipe 4 and an outer spherical case 1, and a second pipe 5 and an inner spherical case 2 are individual from each other and in a contact state. Thereby, microvibration transmitted from an engine along the pipe wall of the first pipe 4 is cut off at a contact part 7 between the outer and inner spherical cases 1 and 2 and hardly transmitted to a position on and rearward of the contact part. During running of a vehicle and especially on an adverse road, bending vibration is generated by the whole of the exhaust pipe. In this case, since, at the contact part 7 of the pipe coupling 9, bending displacement of the first pipe 4 and that of the second pipes 5 are constrained by each other through friction, the pipe coupling 9 is not brought into a free end, the natural frequency of an exhaust pipe system is increased, and the generation of bending vibration and noise in a car is suppressed.
